AMOLED, which stands for Active-Matrix Organic Light-Emitting Diode, is a type of display technology used in many digital devices. It has become popular due to its high-quality visuals and energy efficiency. But how does AMOLED work? In this blog post, we will dive into the inner workings of AMOLED displays to understand how they produce beautiful visuals while still being energy efficient.
OLED Basics
Organic Light-Emitting Diode (OLED) is a type of display technology that uses organic materials to produce light. OLED displays are used in many different devices such as smartphones, tablets, and televisions. OLED displays are different from traditional LCD displays because they do not require a backlight. Instead, each pixel in an OLED display produces its own light. This makes OLED displays thinner, brighter, and more energy efficient than LCD displays.
One type of OLED display is the Panox Display. This is a type of active matrix OLED display which means that each pixel is controlled by its own transistor for faster response times and better picture quality. The Panox Display also uses Color Shift Compensation (CSC) technology to improve color accuracy and reduce color shift.
The Structure of an AMOLED Pixel
An active-matrix organic light-emitting diode (AMOLED) display is composed of a thin-film transistor (TFT) backplane and an organic light-emitting diode (OLED) array. It is a type of LED display technology used in many modern smartphones and other electronic devices. The structure of an AMOLED pixel consists of three components: the TFT layer, the Panox display layer and the organic light-emitting diode (OLED) layer.
The TFT layer is a thin-film transistor which is responsible for controlling the current flow from the display driver to the OLED layer. It also provides an electrical path between the source and drain terminals. This layer helps reduce power consumption and increase the picture quality of the AMOLED display.
The Panox display layer is a proprietary material developed by Samsung that offers high transparency and low power consumption. This layer is placed between the TFT layer and the OLED layer, providing an electrical insulation that keeps the two layers apart. This helps to prevent any interference between the two layers, leading to a more stable operation.
The OLED layer is made up of organic materials that emit light when current is passed through them. The brightness of this layer can be controlled by varying the amount of current passing through it. As well as emitting light, this layer also acts as an electrical insulator, preventing any leakage of current between the OLED and TFT layers.
The Advantage of an AMOLED Display
One of the biggest advantages of an AMOLED display over a traditional LCD or Panox display is its level of brightness. AMOLED displays can produce much brighter colors than LCDs, allowing for better visibility in bright environments like direct sunlight. Additionally, AMOLEDs require significantly less energy than LCDs, resulting in longer battery life for mobile devices. Additionally, since each pixel in an AMOLED display is individually illuminated and does not require a backlight, blacks are displayed much deeper than on a standard LCD display. This results in much higher contrast levels which can be appreciated in any content, from text to videos and games.
The Disadvantage of an AMOLED Display
AMOLED displays have one major downside that needs to be considered when making a purchasing decision. While they offer bright, vibrant colors and good contrast, they are not as durable as other display types such as LCD or Panox displays. AMOLED displays are vulnerable to “burn-in”, which is where the image of a static image is permanently imprinted on the screen due to it being left on for an extended period of time. This is less of a problem for regular users, but it can be a major issue for professional applications. Additionally, AMOLED displays are typically more expensive than other display types.
